FREDERICK C. BERWICK, OF NEW YORK, N. Y.

NAUTICAL SIGNAL.

Specification of Letters Patent.

Patented April 9, 1907.

Application filed March 11,1905. Renewed October 13,1906. Serial No. 338,843.

To all whom/'it may concern:

Be it known that I, FREDERICK C. `BER- WICK, a citizen of the United States, residing ing to be' a full, clear, and exact description of the invention, such as will enable others ,skilled in the art to which 1t appertains to make and use the same.

This inventionrelates to that class of sigi nals commonly styled nautical signals; and it-has for its prime object a simple and effective means for warning approaching and o passing vessels at night or in of ossible danger.

Other objects of the invention will become apparent upon a detailed descri tion thereof. The invention consists in com ining with a oggy weather noise-producing device, such as a whistle, a Vlight which may be iiashed or caused to glow for a given lengthof time, both whistle and light being operated simultaneously.

The invention further consists in the novel arrangement and combination ofthe several parts, as will be hereinafter fully described in this specification and briefly stated in the claim. f

The gure 'in the drawing is aside elevation of my combined whistle and'liht signal.

Referrlng to the view illustrate the numeral 1 indicates'a suitable pipe, which may be located at any convenient place and connected to either a steam or air source of supply. The u per end of the pipe is provided with a whist e 2 of ordinary construction, and a valve 3 is provided to allow the air or steam to escape through the whistle. The valve is operated by a s ring-controlled lever 4, to the free end of w ich is connected one end of a cord 5,l the other end of the cord being atrtached to one arm of a bell-crank lever 6. An

operatin -cord 7 is attached tothe other arm o the be -crank lever.

Secured to ythi pipe 1 'at any desired oint is a bracket 8, in w ich is supported a amp or lantern 9, preferably incloslng an electric light. (Shown in dotted lines.) Current to the electric light is supplied from a battery 10 over wires l1, 12, and 13, which pass through a tube or ipe 14. One end of the wire 12 is connected with a contact-plate 15 and one end of the wire 13 is connected with a post 16, tov which is attached a spring-arm 17, provided with a contact-plate 18. The bell-crank lever 6- is provided with a circuitbreaker/'19, which normally holds the arm out of contact with the contact-plate 15.

A pull on the cord 7 causes' the withdrawal of the post 19 fromthe end ofthe arm, allowing said arm to make contact with plate 15, thereby closing the circuit and supplying current to the lamp. At-the same time the circuit is closed by the release of the arm the cord 5 is caused to operate the lever 4 and 'blow the whistle.

While I have shown the lamp supported upon the bracket secured to the pipe 1, it will be obvious that it may be secured or located at any convenient lace, and it will be understood that other c anges, such as details of construction, may be made without limiting the scope of my invention.

Having thus full described my invention, what I claim, and esire to secure by Letters Patent, is

' The operation of the device'y is as follows:-

In a nautical signal, the combination of a In testimony whereof I aiiix my signature v in the presence of two witnesses;
